The Glue I used is a 2 part epoxy from Devcon called Plastic Welder II. It says it is good for glueing nylon 6.6 which is a common material for intakes.

Well it has been a long time since I did an update. I have now driven the car more than 3000 miles. I have hooked up the heater hoses and got the blower working again. Replaced all the struts with KYB adjustable ones. Still no powersteering but I have the brakes working well. Still lots of little issues but nothing that keeps it from driving.So far the biggest failure I have had was shifting to second one day I broke a weld on my shift lever. I ended up in neutral with no way to select gears. Luckily I carry a small tool kit and I took apart the shfter boots and managed to stuff it into a gear 3 rd I think and drive home. I welded it better this time and added more reinforcement.I've been really happy with my intake and the glue is holding well. Even in freezing temperatures.
